Objective: to assess the prevalence of common mental disorder (CMD) and to identify potential associated factors among medical, dental and nursing students.
Methods: a cross-sectional study conducted in a public university in Northeast Brazil with 172 undergraduate students of the last three semesters of the medicine, dentistry and nursing courses, in February 2010, using the Self Reporting Questionnaire (SRQ-20) and a structured questionnaire developed by the authors. Logistic regression was performed for data analysis.
Results: the prevalence of CMD was 33.7%. The courses presented no differences in CMD prevalence. The logistic regression analysis showed a strong association of the following variables with CMD: female (OR=4.34), lack of good expectations regarding the future (OR=5.83), course as not a source of pleasure (OR=7.52) and feeling emotionally tense (OR=11.23).
Conclusion: the high prevalence suggests that immediate preventive measures should be implemented, such as the setting up of psycho-pedagogic support services for students, and teacher development programs.
